Hi! I’m Allen Carson Cohen (aka, Allen C Cohen and Allen C. Cohen)

I am a research professor in the Department of Entomology and Plant Pathology at North Carolina State University where I coordinate a program in Insect Rearing Education and Research.  I recently published the book, Insect Diets: Science and Technology 2nd Edition from CRC Press.  I teach online courses in insect rearing and have taught 6 face-to-face courses in rearing to try to help people interested in producing insects to become more aware of the science and technology involved in propagation of high quality, reliable insects.

I have finished a new book on Design, Operation, and Control of Insect Rearing Systems also from CRC Press. This book is slated to be published in May, 2021. It contains chapters on historical background of insect rearing such as 5,000 years of silkworm rearing and how Drosophila rearing was the basis for many of the most commonly-used practices in contemporary insect rearing systems. The new book gives insights into how rearing systems are artificial ecological niches. It covers detailed information about rearing education, providing actual examples from the classes that I have. taught over the past 20 years. Another valuable part of the new book is its treatment of quality control and process control, both of which are approached from the perspective of Douglas Montgomery’s design of experiments. I treat the approaches to design of experiments with tutorials that give a step-by-step explanation of how to use JMP statistics programs to design rearing experiments.

Another recent commitment that I have undertaken is to serve as an editor of the open access journal Insects:


The journal Insects publishes a variety of high quality papers on insect science, including papers dealing with insect rearing. Currently, Insects is developing a special issue on the Science and Technology of insect rearing systems where papers on all aspects of insect rearing including nutrition, processes, insectary genetics, microbial issues, physical/chemical aspects of rearing (such as diet texture analysis, gas exchange determinants, chemical aspects of diets), and rearing system environments (to mention a few of the acceptable topics). Authors are especially encouraged to present papers that deal with conventional and novel perspectives of rearing system science and technology, and clear statement of the rationale and hypotheses behind rearing studies are greatly encouraged.
